What is Sildenafil?
Sildenafil is an active ingredient in many drugs used to treat erectile dysfunction (ED) in men. It belongs to the class of inhibitors of phosphodiesterase type 5 (PDE-5), acting at the level of molecular processes in the cavernous body of the penis, contributing to the emergence of an erection during sexual arousal.
The original drug developed on the basis of sildenafil is Viagra , but there are numerous generics that also contain this substance.
How does Sildenafil work?
The mechanism of action of Sildenafil is that it blocks the action of the enzyme phosphodiesterase type 5 (PDE-5). This leads to the accumulation of cyclic guanosine monophosphate (cGMP), which is responsible for the relaxation of smooth muscles in the walls of blood vessels of the penis. As a result:
- Blood circulation in the cavernous bodies of the penis improves .
- An erection increases in the presence of sexual excitement.
Sildenafil is effective only under conditions of sexual stimulation, that is, it does not cause an involuntary erection.
